This inverter layout is designed to abut to form a ring oscillator.  Notice the Metal 2 trace above the IN/OUT.  This provides the return path from the output of the last inverter to the input of the first inverter in the ring oscillator.

Example Layouts

Inverter

Shown below are several different ways to layout an inverter:

Layout 1
Tutorials-Cadence-ExLayout-Inv-001.png
Area = 7.80um x 10.80um = 84.24um2


Layout 2
Tutorials-Cadence-ExLayout-Inv-003.png
Area = 7.80um x 13.20um = 102.96um2


Layout 3
Tutorials-Cadence-ExLayout-Inv-004.png
Area = 7.80um x 10.80um = 84.24um2


Layout 4
Tutorials-Cadence-ExLayout-Inv-005.png
Area = 7.20um x 16.20um = 116.64um2

This inverter layout is designed to abut to form a ring oscillator. Notice the Metal 2 trace above the IN/OUT terminals. This provides the return path from the output of the last inverter to the input of the first inverter in the ring oscillator.
